To all whom it may concern.- section on the line 00, Fig. 2; and Fig. 5is Be it known thatI, GEORGE H.

As is usual,

IO Several forms of staple-like fastening de the legs are beveled attheir ends and are vices have been devised for securing in place bent ata, where they join the crown. The the covers or tops of wooden boxes,tubs, or central portion of the crown retains the shape other similarvessels, the device comprising, and diameter of the blank; but at eachend, essentially, two driving legs or prongs and adjacent the bendsa',the crown is swaged or 15 a connecting-crown, the latter being .bentflattened, as at b, the swaging extending to around the corner of thebox or tub to which the tops of the legs. This swaging serves by thefastening is applied. its compressive action to not only harden the Inpractice the fastening devices are usucrown adjacent the legs, therebyimparting 7o ally made of tinned or coppered wire shaped the desired andnecessary stiffness thereat,
